WebLiquid metal induced embrittlement (LMIE) is the reduction of the fracture resistance of a solid material during exposure to a liquid metal. This article discusses the mechanisms and occurrence condition of LMIE and describes the effects of metallurgical factors, such as grain size, temperature and strain rate, stress, inert carriers, and fatigue, on LMIE. WebThe susceptibility of the ferritic–martensitic steels T91 and EUROFER97 to liquid metal embrittlement (LME) in lead alloys has been examined under various conditions.

Previous studies on T91 steel in its standard metallurgical state do not provide evidence for liquid metal embrittlement by eutectic Pb–Bi. In this paper, we show that this steel can be embrittled by Pb–Bi when direct contact between the steel and the liquid metal is obtained by prior ion beam sputtering of the native oxidized film. how many people are on death row in pa
